Discussions By Symptom: Dizziness

Cannot get a diagnosis. In dire need of help!

I have been sick for 8+ weeks now. It started with seasonal allergy symptoms and has slowly gotten worse to the point where I can hardly function. I was told it was allergies, then a cold and allergies, then a sinus infection and UTI, then a sinus infection UTI and a drug reaction to antibiotics. Now I have so many symptoms I don't know what could be causing them. I have dizziness to the point of intense vertigo, a dull headache that hasn't gone away once and sometimes gets sharp, a stiff neck, chest pain, numbness and tingling in extremities, heat sensations all over my body (like I am standing too close to a heater), twitching muscles (particularly in face), nose congestion that won't budge, more sneezing than normal, mild nausea, extreme fatigue but unable to sleep much, confusion/fuzzy head/mild forgetfulness, loss of balance, lose stool, some uterine pain; I feel like I am losing my mind! I can't get a diagnosis and I've seen my primary doctor, walk in doctors, been to the ER and no one seems to think it's serious at all. Please help!
